Scintil Photonics secured $58M to scale integrated photonics for AI factories

Grenoble-based Scintil Photonics, a
company developing integrated Photonic System-on-Chip (PSoC) solutions for AI
infrastructure, has closed a $58 million Series B round. The funding will drive
global hiring, accelerate production, and expand its international footprint as
it launches the industry’s first single-chip DWDM light engine.

Built on its proprietary SHIP™
(Scintil Heterogeneous Integration Photonics) process, Scintil’s technology
integrates lasers, photodiodes, and modulators onto a single chip, replacing
dozens of discrete components to deliver higher performance, efficiency, and
density for next-generation co-packaged optics (CPO).

Drawing on more than 15 years of
research at CEA-Leti, one of Europe’s leading semiconductor institutes, the
company has a strong head start in heterogeneous silicon photonics.

The Series B funding supports the
commercial ramp of LEAF Light™, the industry’s first PSoC DWDM-native light
engine, aligned with next-generation co-packaged optics (CPO). DWDM (Dense
Wavelength Division Multiplexing)-native means the single-chip device can
output many precisely spaced wavelengths, dramatically increasing bandwidth
while lowering energy use. By reducing power per bit, LEAF Light™ also helps
cut the carbon footprint of AI data centres.

Matt Crowley, CEO of Scintil Photonics,
shared:

This investment marks a pivotal moment for Scintil as we
move to full-scale deployment. Our SHIP™ technology enables integrated photonic
solutions with the scalability, energy efficiency, and integration density
required to power next-generation compute infrastructure. This efficiency not
only reduces data centre operating costs but also contributes to lowering the
carbon footprint of AI infrastructure.

With LEAF Light™ entering high-volume production, we’re
expanding from our base in Grenoble into the international markets, including
the US, to support the world’s most advanced AI factories.

Built on Scintil’s SHIP™ platform,
LEAF Light™ enables low-power, high-density optical connectivity, delivering
6.4 Tbps/mm edge bandwidth density today, at roughly one-sixth the power
consumption of conventional pluggable solutions. It’s designed for scale-up GPU
clusters and emerging AI systems, with reference packaging and integration
support to accelerate deployment.

The round was led by Yotta Capital Partners and NGP Capital, with strategic participation from NVIDIA and
continued backing from global and regional deep tech leaders. Existing
investors Supernova Invest, Bpifrance, and Innovacom also joined, alongside prior
strategic backers Robert Bosch Venture Capital (RBVC), Applied Ventures, and
ITIC-Taiwan, reaffirming their strong confidence in Scintil’s technology
platform and market potential.

Vincent Deltrieu, Managing Partner at
Yotta Capital Partners, said:

Scintil exemplifies the kind of innovation leaders we look
for, combining advanced manufacturing, deep-tech leadership, and meaningful
impact on the energy demands of AI infrastructure. Scintil’s integrated
photonics platform is essential to scale the next generation of AI factories.
We’re excited to support their global growth as they move to high-volume
shipments.

Bo Ilsoe, Managing Partner at NGP
Capital, added:

Integrated photonics is becoming a foundation of all AI
infrastructure, and Scintil is turning that future into reality. Their
technology delivers the bandwidth density and energy efficiency AI factories
require with global scalability. We’re excited to support Scintil as they scale
deployments and become a leading player in building the next wave of compute
and data infrastructure.

The funding will allow Scintil to
accelerate hiring and strengthen its US presence while continuing to build from
its strategic base in Grenoble. Situated at the centre of Europe’s advanced
semiconductor ecosystem, the company benefits from close ties to institutions
like CEA-Leti and leading global players in the region, giving it access to top
talent and a collaborative innovation environment.

Backed by leading investors and
trusted by industry pioneers, Scintil is well-positioned to provide the
integrated optical technologies required by next-generation AI factories.
